Argh!! remind me not to use his company!!!

Unless somebody has a good excuse, like Katrina hit, no contractor who is worth a dime is going to start a job, expose the roof deck, and leave for months.. Even if they use deck armor. Ice and Water, in the GAF Weatherwatch brand, doesn't allow unlimited exposure. I think it is between 30 and 60 days max.

Iquote=warnerww;48692]My brother is a roofer in the Seattle area where it rains all the time and they put that stuff down and then leave for months to do other jobs then come back and roofs later. They are so busy he told me that is the norm and he has never had a problem. We are talking commercial buildings with hundreds of squares for one job. The stuff really works.[/quote]

That is they way it is. These guys do not even advertise. Their is no way to get a hold of them other than word of mouth. They are not in the yellow pages they do not advertise at all. They are considered the best of the best. They will not even look at hiring you unless you have been on the roof for at least 10 years. These guys know their stuff and get paid for it. They work hard but the actually get 4 days paid vacation which if you are a roofer you Know how rare that is. At least that is rare in my experience. Most construction people work and get paid or do not work and do not get paid.

I will look into other products. I also want to give my local building inspector a call before using it. I just don't want any surprises. How about using double 30# paper? This stuff is pretty thick. Do you think it has the possibility of pushing up the shingles?

The pitch is 4 in 12. I guess that would be considered a low pitch. I am definitely going to use ice and water in the valleys and where I think a leak may occur. I'm just want to explore my options. I'll get some prices on other ice and water products today. The only thing that appears to be a turn off to 100 percent ice and water is condensation issues/ breathing issues. I am planning on running a ridge vent across the entire roof with 100 percent soffits, so I'm guessing ventilation will not be an issue. Another issue is removing the ice and water for the next replacement. I know that it is impossible to remove. I don't know how the building inspector will handle the situation when a reroof is necessary in 20 years. Sheathing inspections are required in my area.

If it is installed correctly, does not leak, and has 100 % balanced intake and exhaust ventilation as you stated, unless the decking is already starting to show signs of delamination and feel crunchy to walk on, 20 years from now, it will still be in good shape.

Put the felt paper over the top of the Ice and Water Shield if you are concerned about the shingle sticking to it during the next tear-off 20 + years down the road.

Wow! Grace is expensive. The cheapest I have found is $90 for two squares and $63 for a one square package. It cost just as much as a square of 30 year architectural shingles. I'll check other brands, but I can't justify spending that much.

Regarding I & W shield. Which one do you guys prefer. I have always been a Grace Vycor Plus user, but the cost runs between $ 82.00 to $ 91.00 per 67.667 foot roll from 2 of my suppliers, being only 2 squares.

P.S. I charge $ 3.00 per lineal foot or $ 1.00 per square foot for it. Is that in your guys ballpark. It doesn't seem too expensive in my opinion, but I am getting way undercut this year, by everybody!!!

Too many illegal subcontractors flooding the market-place in the Chicago area going completely unchecked.

At $45 a square ($90 for two square roll). I'm looking at $1080 to do the whole house. That is a significant cost. I just can't see myself spending that money for a 4 in 12 slope roof. If it was 3 in 12, I would probably go for it. That stuff is expensive. Grace must be making a killing on that stuff. Winterguard will run me $780. A double layer of 30# runs at $240. If I could get the price around $500 to $600, I would probably jump on it. Any other brands that I can check the prices on.

Check with a roofing wholesaler not a lumber yard. Try Brado or ABC. other brands are Carlile, JM, GAF,IKO,Henry EaveGuard and many more. call around some suppliers and tell them you want a generic I&W. its still way better than paper.

deck armour, ice and water, 30# felt

I am going to use two rows of IW from the eaves.. Then 3o# felt up to the peak where I will use IW again because I am going to put in ridge vents. Any particular brand of vent tickle your fancy?? I used the Cobra mesh once, it seems ok. Would like a plastic prouct for straight lines. But, the one used on my garage lets little tree particulates in.. No mesh screen, just some hoaky diverters.

What has been the report on the GAF Deck Armour breathable membrane?

Man, I want to use this stuff bad, but I can't get it in my budget. It must be nice to buy in bulk and get the discount. I went to ABC Supply and was quoted $50 for GAF 1 1/2 squares. Basically, it is the same price as Certainteed per square. I couldn't remember the other names you mentioned and he didn't know of any others off the top of his head. I'll go back tomorrow when it isn't busy and ask him to find the cheapest ice and water they stock. As for now, my plans are to cover the leak prone areas with certainteeds brand. I still will have to run felt though . I'm wondering if ice and water will eventually replace felt and be code. I have been reading about it and it does sound like a great product. The price will definitely go down if it is the status quo underlayment. Since I might be looking at running felt. Which one of these would you use on a 4/12 roof.

1. Single layer of 30# with the normal 2 in overlap.
2. double layer of 15# with 19" overlap.
3. double layer of 30# with 19" overlap.

Bradco Supply generally has a way better price than ABC or Harvey, Beacan Sales has great prices as well if there in your area. best bet is to call tham on the phone and get some quotes and some info. In my area all 4in 12 roofs are done full I&W because they are considerd to be low slope. and the lower the slope the more likley a problem.
